3 Signs That Your Furnace Needs Replacing

Winter is here, and it’s time to evaluate whether or not your furnace can get you through another cold season. If your system isn’t up to the task, it’s best to replace it now before the coldest weather arrives. You don’t want your furnace to give out on you in the middle of one of the coldest months of the year. With that in mind, keep an eye out for these 3 signs that your furnace needs replacing.

ONE: Efficiency

Older furnaces have more wear and tear on their systems, which means that their efficiency drops the older they get. As the efficiency of the system declines, the furnace has to stay on for a longer and longer period of time in order to affect the same temperature changes. This is reflected in higher heating bills. If your heating bills are rising for no apparent reason, it may be time to replace your furnace.

TWO: Repairs

As the wear and tear on the system mounts, the various parts of the furnace will start to break down. Each part wears down slightly differently, so as the furnace ages it becomes more and more likely that you’ll have multiple parts break down within a few weeks of each other. Under normal circumstances, a furnace shouldn’t need repairs more than once or twice a year. If you have to repair your furnace ever few months or so, it’s a good idea to replace it.


Furnaces are manufactured to last around 20 years. Past that point, they start to develop problems like those listed above. The older a furnace is, the more it will cost to keep it operating properly. If your furnace is older than 20 years, you’ll save far more money in the long run by just replacing it.
